Paul Sokolovsky	d5e9ab6e61	extmod/machine_pulse: Make time_pulse_us() not throw exceptions. machine.time_pulse_us() is intended to provide very fine timing, including while working with signal bursts, where each transition is tracked in row. Throwing and handling an exception may take too much time and "signal loss". So instead, in case of a timeout, just return negative value. Cases of timeout while waiting for initial signal stabilization, and during actual timing, are recognized. The documentation is updated accordingly, and rewritten somewhat to clarify the function behavior.	2017-02-05 14:20:17 +03:00

extmod/machine_pulse: Make time_pulse_us() not throw exceptions.

machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.
